UTP CAT5 Version 2

If any cab bus item is 30 feet of cable or more from the command station you will need to inject power into the cab bus to make sure a clean signal of minimum 8v gets out to the the devices on the cab bus.  

The overall goal is this:  A minimum of 8v DC as measured on the UTP Panel and cab bus cables between pins 2 and 5  / Black and Yellow.

5240207 The “regular” UTP - 1/8inch (3.5mm) (Mono mini headphone jack) on the back of the UTP. The tip of the plug is positive (+) and the sleeve is negative.

5240234    UTP-Cat5    Additional power for the Cab Bus can be added to the socket in between the Cat5 sockets. We suggest a 1/2 to 2 Amp, 12 to 14Volt, Regulated DC power supply such as the NCE P114. (5.5/2.5mm plug center +)

If you have a  regular UTP but want to add the P114 for added cab bus power, you will need to hack off the end and add the male 1/8inch (3.5mm) (Mono mini headphone plug)   or solder the P114 directly to the board

 

Same six-wire connectors in front as UTP but allows use of off-the-shelf CAT5 cables to connect panel-to-panel at rear. Can be used as a cab bus splitter, and also adds the abilty to add power to the cab bus for larger layouts. 

The new version has 6 jacks total. 4 RJ12 ( 2 front/ 2 side) / 2-RJ45 in the rear. The 4 RJ12 are standard NCE Cab bus jacks. The 2 RJ45 are standard computer ethernet cable jacks.

The part number is 524-0234. The price went up $5 when the 2nd set of jacks were added on the newer version  click here to buy a UTP-CAT5 now 

To use this for power injection on a long cab bus add the P114 Power Supply. Go here for information on the P114

Additional power for the Cab Bus can be added to the socket in between the Cat5 sockets. We suggest a 1/2 to 2 Amp, 12 to 14Volt, Regulated DC power supply such as the NCE P114. (5.5/2.5mm plug center +) The switch on each UTP-Cat5 should always be in the “NORM POWER” position. Only switch it to “EXT POWER” on panels that have an additional power supply connected. Please Note: The UTP-Cat5 printed circuit board is marked on the upper, right corner that says “CMD STA” with an arrow. This indicates that the cable from the Command Station (Cat5 or six wire) should plug in here.

 

The overall goal is this:  A minimum of 8v DC as measured on the UTP Panel and cab bus cables between pins 2 and 5  / Black and Yellow.
